RING-SPINNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 454,823, dated June 23,1891.

Application filed July 10, 1890. Serial No. 358,281- (No model.)Patented in France June 4, 1886, No. 176,558 and in England July13,1888, N0.10,205.

To aZZ whom it may concern.-

Be it known that I, J OsEPH IMBs, a citizen of France, residing atParis, in the Department of the Seine, France, have invented a new anduseful Improvement in Ring-Spinning Machines, (for which I have obtainedpatents in England,No. 10,205, dated July 13, 1888, and in France, No.176,558, dated June 4, 1886,) of which the following is a specification.

Myinvention relates to improvements in spinning-machines, part of whichimprovements-namely, that relating to the drawingrollers-is applicableto preparatory machines. In carrying out the first part of my inventionI reduce the frictional resistance brought about by the tension of thespindle cords upon the collars of the spindles, either in self actingmules or in throstle frames. For this purpose I substitute for theordinary collars .of any arrangement friction-rollers, which are not incontact with but in close proximity to one another and upon which thespindles revolve. These rollers, driven by the spindles upon which thecords bear, rotate with a very reduced speed. I inclose them so as toshelter them from dust, and I further provide their axles with acontinuous-oiling arrangement.

In the accompanying drawings, Figures 1 and 1 are views in verticalsection; Fig. 2, a plan showing two-neighboring spindles, and Fig. 2? adetail. Figs. 8, 8 and 4 illustrate the application of the invention toring and traveler throstles, Fig. 3 being a sectional elevation, Fig. 3a plan, Fig. 4 aside elevation, and Fig. 5 is a detail view of animprovement hereinafter described. Fig.6 is an elevation showing devicesthat may be used to move the ring-plate and yarn-guide in oppositedirections.

Bis a spindle with its whirl b, (which in ring and traveler throstlesmay be placed either above or below the plate-bolster P.)

C is the cord proceeding from the drivingdrum. The plate-bolster P. isprovided with perforations through which the spindles B pass freely.

The friction-rollers G, which are of large diameter relatively to thespindles B, are arare made of hard wood and are provided each with athin gun metal core f, which turns on the axles g. groove 4' in theplate-bolster, being prolonged beneath the rollers. The groove 1' formsan oil-reservoir. As shown in Figs. 1 and 2, the plate P is providedwith an exterior groove 10, and with channels 8, which communicate withthe interior groove 4'. As shown in Fig. 1 the oil will be drawn up bythe rotation of the core f, and. will return by a passage e through theinterior of the fixed axle g. The continuous oiling of the axles is thusoffected.

The spindles B bear directly against two adjacent rollers, there beingone spindle in each space between the rollers. The spindles being ofsmall diameter may be driven at a very high speed, while the rollersthemselves will rotate at a much reduced speed. This arrangement of theordinary mule-j enny spindles is found very advantageous. v

A plate P, Figs. 1 and 3,incloses and covers the space in bolster Pwhich contains" the rollers, said plate extending to the spindles B. Infront of the spindles upon pins 25, fixed to the bolster P, is a rail orbar R, carrying horizontal plates u a, which are designed to preventrearward vibration. The bar R is adjustable. As shown in Fig. 1, itsadjustment is effected by means of the nuts R R which, in moving the bartoward the plate-bolster, compress the small springs s. In theconstruction shown in Fig. 3 the pinthas ahead If for turning, and thespring 8 is between this head and the bar R.

The foot of the spindle may rest, as usual, in a step-bearing; but thespindles being practically vertical must have a support from theoutside. To this end the projecting plates u a may extend sufficientlyfar to make contact with the spindles. In this case the construction ofFig. 3 shows a convenient arrangement in which, after the bar is set tothe proper position by screws t, the spring 8 holds the edges of thesupports u it in light contact with the spindles. It is also desirableto place against each spindle a rest or bearing 00, mounted on aregulating-screw V, which is tapped into the flange of plate P. Eachspindle is provided with a brake-such as the These cores f rest in a logpiece y, Figs. 3 and 3 whichis a brake-lever adapted to be operated bythe knee of the workman, and to be pushed either right or left.

In Figs. 1 and 2 is shown a bolt-brake f, which form is preferred. Theconstruction is best shown in Fig. 2 in which the brake is seen out ofcontact with spindle B. The edge of the brake on the right side of thespindle is inclined, so that by moving the brake forward the spindlewill be separated from the rollers G and wedged against the adjacentparts a a or the rest or hearing so.

In order to utilize in ring and traveler throstles the excess of speedwhich is obtained by the construction and arrangement of the spindles,as hereinbefore described, it is desirable also to relieve theresistance of the travelers upon the ring, which resistance becomesparticularly injurious in cases when in making conical bobbins thetraveler is winding on the summit of the cone-that is to say, upon avery small diameter. This result may be obtained at the desired momentsby the following construction, as shown in Fig. 4:, which is or may beas usual in this class of machines.

I place tightly on the top of the spindle a light disk or cap M, havinga diameterabout equal to that of the ring N. This disk or cap, as willbe readily understood, may be removed in order to effect the gatheringof the bobbins. It is of circularform but its shape and material may bevaried according to requirements. I may make it of solid and archedsheet metal or of other suitable material or form. The yarn coming fromthe guide in order to descend upon the traveler n, necessarily isdeflected inwardly around the disk or cap M, upon which it finds abearing-point. The rounded and more or less polished edge of this diskor cap thus tends during the rotation of the spindle to constantly urgethe yarn forward and pull the traveler 11. On the other hand, .the anglea, between the yarn and disk, depends, as shown in the figure, on thedistance at which the guide m is placed above the spindle. I cause thesaid yarn-guide m, by acting on its supporting-rail M to move verticallyin a direction contrary to that of the bolster P of the ringsthat is tosay, the yarn-guidem is gradually lowered to the positions indicated bym and m while the bolster P rises to effect an ascending winding, andvice versa. The limits of travel of the yarn-guide from m to m and to mmay be constant in length or position, or gradually varied and broughtnearer to the top of the spindle in proportion as the making of thebobbin progresses. The angle a always becomes smaller in proportion asthe bolster P" carries the yarn onto the smaller diameter of the cone,and hence in proportion the tension of the yarn tends to increase inorder to pull the traveler. The increase of the tension on the yarn andthe closing of the angle a thus simultaneously cause a proportionateincrease of the drawing action exerted by the disk or cap M upon theyarn and upon the traveler. By thus regulating the resistance of thistraveler and the effective tension of the yarn it is possible to utilizethe whole of the speed which it is desired to impart to the spindles.

Various means may be employed to give the desired motion to the plate Pand yarnguide 071.. In Fig. 6 I have shown devices that may be employedfor the purposes specified. The bolster-plate P is carried by a rod T",whose lower end rests against one arm of a bell-crank lever WV, itsother end being connected by a cord passing around pulley W with the endof an arm B which is pivoted on a lever 0 Arm B has a bearing againstthe cam A, which, by moving said arm, raises the bolster-plate P". LeverG which is pivoted at 19 is oscillated by a cam A and its movements areimparted to the rail M which carries the yarn-guide m. These movementsare communicated to the bell-crank lever y y y and the arm 1/ acts on aroller 00 carried by an arm depending from rail M The bell-crank levermay be connected directly to the lever C at c by a rod (indicated bybroken lines) T, or it may be connected to an intermediate lever D by arod T lever D being connected by T to the lower end of lever O at 0 Fig.4 shows likewise a general view of a ring and traveler throstle as Iarrange it, and provided with improved means for use in drawing yarn.Fig. 5 shows separately a section of this improvement, which isespecially applicable to a case in which materials having very irregularfibers have to be spun, and which furnish slivers containing many shortstaples or fibers mixed with long ones, and even with knots or burrs, ashappens with cotton waste, for instance. The use of ordinarydrawing-rollers does not allow the regular drawing of such slivers, asit is not possible to place the rows of rollers in very close proximityto one another, as would be required for short fibers, and, furthermore,a very slight separation can never be attained with ordinary rollerswhose decrease of diameter has a limit.

I feed the so-called drawing-rollers D D by a roller A, provided with acovering-cap O, forming a prolonged and polished contactwith the rollerA and on which it lies, either by its natural weight or by meansofadditional pressure. This cap is supported in slides upon thecarriage, as indicated in dotted lines. It may thus be adjusted aroundthe feed-roller, and may also be removed read ily, or its pressure maybe regulated by ordinary adjusting means. It will be observed that therollers are mounted on the carriage, that they have a decided hitch orinclination, which is advantageous for continuous spinning.Notwithstanding this inclination the yarn or roving leaves thefeed-roller tangentially, or nearly so. This arrangement is adhas beenproposed to arrange fliers to rotate against flanged rollers, and thatrings surrounding the spindle proper have also been provided withbearings against collars or friction-rollers. According to my inventionthe spindle itselfthat is, the slender axle, which is the spindleproper-is caused to rotate directly against rollers of large size.

This improvement in effect furnishes a new spindle in connection withring-throstle systems, giving superior results.

Having now described my said invention, what I claim is 1. Thecombination of the bolster-plate, the mule-jenny spindles passing freelythrough the same, friction-rollers of relatively large diameterjournaled in said bolster-plate, said spindles each rotating directlyagainst and between two adjacent rollers, and the drivin g-cords whosetension holds the spindles against their supporting-rollers,substantially as described.

2. The combination of the bolster-plate, the spindles passing freelythrough the same, and the friction-rollers inclosed in said bolsterplateand forming bearings for said spindles, said bolster-plate beingprovided with oil-pas sages leading to the inclosed bearings of saidfriction-rollers, substantially as described.

3. The combination of the bolster-plate having at the bottom an interioroil reservoir or channel and an upper oil channel or passagecommunicating therewith, the friction-rollers provided with coresprolonged beneath said rollers and resting in said oil-reservoirchannel, and spindles resting against said rollers, substantially asdescribed.

4. The combination, with the spindles, the friction rollers inclosed inboxes through which the spindles pass, said spindles being held by theaction of the driving-cords against said rollers, of the supports (suchas plates 1/. u) on the side of the spindles opposite to said rollers,substantially as described.

5. The combination, with an inclined carriage and drawing-rollers andfeed-rollers mounted thereon, of a cap resting freely upon thefeed-roller. and inclined away from the drawing-roller, and adjustableslides in which said cap is supported, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
